SPECIFICATION forming part of Letters Patent No. 671,027, dated A rn 2, 1901.

Application filed December 23, 1899. serial No. 741,423. (No model.)

To all whom it may concern:

Be it known that we, ADOLPH J. PETTER, residing in the city and county of San Francisco, and EDWARD J. KILLIAN, residing in the city and county of Los Angeles, State of California, citizens of the United States, have invented certain new and useful Improvements in Foldable Roller Carriages or Chairs; and we do hereby declare the following to be a full, clear, and exact description of the same.

The present invention relates to certain new and useful improvements in roller carriages or vehicles for invalids or children; and it consists in the arrangement of parts and details of construction, as will be hereinafter fully set forth in the drawings and described and pointed out in the specification.

The object of our invention is to provide a simple and inexpensive roller carriage or chair having its parts so united as to permit of being quickly folded into a small package or parcel capable of being carried in the hand when boarding transportation-conveyances or for shipment from place to place and easily restored into proper position when desired for use.

In order to comprehend the invention, reference should be had to the accompanying sheet of drawings, forming a part of this application, wherein- Figure 1 is a perspective view of the carriage set up and ready for use. Fig. 2 is a similar View showing the carriage folded, and

Fig. 3 is a broken enlarged detail, view of one of the rear standards and the extensionback.

In the drawings the letter A is used to indicate the rear wheels of the vehicle, and A the front wheels thereof, which Wheels are secured, respectively, between the curved bi- These arms or supports are curved, soas to place the wheels in alinement with the rear and front standards B B, and they are connected at their upper ends to the said rear and front standards B B, respectively, by swivel-joint a. The rear standards B are somewhat longer than front standards B, and the standards are detach-ably connected by suitable connecting devices, as braces l 2 3. These braces at one end are pivoted to rear standards B by pins a and attached to forward wise constitutes the back of the vehicle, and

it is supported intermediate the hinged footrest and slide-bar O by means of the crossrods D D. The slide-rod works upon a post or posts b,secured to and upwardly projecting from cross-rod D and the same is normally held upward by means of the springs W, interposed between the slide-rod and the crossrod D By this arrangementa spring connection, so to speak, is provided for the seat of the vehicle, which permits of the seat giving during travel of the vehicle over rough or uneven surfaces and by reason of such give or spring action prevents the invalid or person seated therein being subjected to jarring, which would result in case the spring connection be dispensed with.

To the back or rear standards B is connected an extension-back consisting of side pieces E, united at their upper ends by crosspiece d. The side pieces E at their lower ends are provided with an inwardly-projecting stud or button d, which fits within the slotted plate E, attached'to the upper end of each standard B. The extension-back may be swung downward, so as to lie against the outside of the back proper, Fig. 3 of the drawings, and secured into place by any suitable fastening device, or it may be entirely removed by lifting the same, so as to remove the button d from within the slotted plate E. When swung over upon the back proper, Fig. 3, the buttons or studs d rest within the slotted extension d of the plate E. It will be understood that the extension-back is provided with a suitable covering E When desired to make use of the extension back, it is only required to release the same from the back proper of the vehicle and swing the same upward, it turning upon its hinged joint formed by the studs orbuttons working within the slotted shoulders of plates E.

When raised to a vertical position, the lowerend of the extension-back is removed from within the slotted shoulders and permitted to To the extension-back is hinged an awningframe F, over which fits an awning F, Fig. l of the drawings. One end of this awning is attached to the'upper end of the extensionback.- If the awning is not in use, the same is thrown over the extension-back and secured at its lower end to the vehicle proper by buttons f, as illustrated by dotted lines in Fig.1. When thus secured,the awning forms a package-holding receptacle F The wheels A and A are held locked in position by means of the slide-bolts f at the back of each standard B B engaging with the sockets f cut in the upper edge of the supports or arms A A To close or fold the vehicle,the wheels are first unlocked and then turned inward or at a right angle to the body and locked in this position. Braces 1 2 3'are then released and permitted to swing downward and foot-restO sWung upward. Standards B are then laid up against rear standards. The awning-frame being swung inward against the extensionback and said back swung over, the awning will be free to serveras a binder for the entire package. The awning is drawn over the folded parts in order to hide the same from view and is secured thereover by the free end being buttoned, Fig. 2. The other side of the casing is formed by the covering E of the extension-back. When folded or closed together an exceedingly neat and attractive package is provided and one which may be readily handled or transported from place to place.

Having thus described our invention, what we claim as new, and desire to secure protection in by Letters Patent, is

1. In a foldable carriage, the combination with the rearstandards, of the front standards foldably connected thereto, the supportingwheels secured to the standards by a swiveljoint, means for locking the Wheels in desired position the hinged foot-rest, a covering for seat and back of the carriage, said covering being secured at its lower end to the frame of the foot-rest and at its upper end to a slidebar, and of spring connection between the slide-bar and a cross-rod at the upper end of the rear standards.

2. In a foldable carriage or invalids chair, the combination with the rear standards, of the front standards foldably connected thereto, the supporting wheels secured to the standards by a swivel-joint,means for locking the wheels in desired position, a foldable seat for the carriage, means by which jarring is compensated for, an extension-back hinged to the rear standards, said extension -.back serving as a cover for one side when the parts are folded, and of a covering carried by the extension-back and which serves as a covering for the opposite side of the package formed by folding of the parts.

3. In a foldable carriage or invalids chair, the combination with the rear standards, of the front standards foldably connected thereto, the supporting wheels secured to the standards by a swivel-joint, means for locking the wheels in desired position, a foldable seat for the carriage, means by which jarring is compensated for, an extension-back hinged to the rear standards, said extension-back serving as acover for one side of the package formed by folding the parts together, an awning-frame hinged to the extension-back, and of an awning attached to the said back, said awning serving, when the parts are folded, as a cover for the opposite side of the package,

In witness whereof we have hereunto set our hands.
